Question

我有2个组成部分-trial1（父级剑道网格），trial2（子级剑道网格）。在trial1的模板中，我引用了子网格组件trial2。但是我收到一个错误，其中在trial1中无法识别trial2。

<ng-template kendoGridToolbarTemplate>
  <button kendoGridAddCommand type="button" class="btn btn--secondary btn--small addTableRow"><span class="icon-add"></span></button>
  <button *ngIf="formGroup" (click)="cancelHandler()" class="k-button k-primary">Cancel</button>
</ng-template>

<kendo-grid-column *ngFor="let details of dTable.columns;let i = index;" [field]="details.field" [title]="details.title" width="details.width" [editable]="true">
</kendo-grid-column>

<ng-template kendoGridDetailTemplate let-dataItem>

    <trial2></trial2>

  </ng-template>

<kendo-grid-command-column title="command" width="100">
    <ng-template kendoGridCellTemplate let-isNew="isNew">
        <button kendoGridRemoveCommand class="label label--circle label--small btn btn--secondary show icon-presence-end">X</button>
    </ng-template>
</kendo-grid-command-column>

</kendo-grid>

Angular中的解决方案（不是JQuery）将不胜感激。谢谢

请参阅master-detail grid demo 要设置in-cell editing，您需要在主网格和明细网格组件上添加以下事件：-

cellClick->单击单元格时显示输入
cellClose->保存离开单元格上的数据

如何将剑道网格放置在另一个剑道网格中，以便两个网格都可以在单元格上进行编辑？
